Functions ¶

func MarkAsUsedInKDF ¶

func MarkAsUsedInKDF(h *HMAC)

MarkAsUsedInKDF records that this HMAC instance is used as part of a KDF.

Types ¶

type HMAC ¶

type HMAC struct {
	// contains filtered or unexported fields
}

func New ¶

func New[H hash.Hash](h func() H, key []byte) *HMAC

New returns a new HMAC hash using the given hash.Hash type and key.

func (*HMAC) BlockSize ¶

func (h *HMAC) BlockSize() int

func (*HMAC) Clone ¶

func (h *HMAC) Clone() (hash.Cloner, error)

Clone implements hash.Cloner if the underlying hash does. Otherwise, it returns errors.ErrUnsupported.

func (*HMAC) Reset ¶

func (h *HMAC) Reset()

func (*HMAC) Size ¶

func (h *HMAC) Size() int

func (*HMAC) Sum ¶

func (h *HMAC) Sum(in []byte) []byte

func (*HMAC) Write ¶

func (h *HMAC) Write(p []byte) (n int, err error)
